Public Dubbing Event Report

The public dubbing event was held somewhere in Tokyo Friday June 22nd.
Mana Ashida, who plays Largo, Rina Kawaei, who plays Lisa,
Masako Nozawa, who plays Hisui, and Shoko Nakagawa, who plays Riku all took the stage.



Ashida, who plays Largo, greeted the audience,
saying "I'm very happy to be able to take part in the world of Pokémon, which I've been very close to since I was little". She gave us such an excellent performance that the sound director commented how "she does a very solid job playing a strong-willed Largo".
She was then asked what she thought of Satoshi as a boy,
and replied "I thought it was really cool how Satoshi always comes to help Largo when she's in trouble, and I also think he's a boy who's able to understand the feelings of people and Pokémon, consider those feelings, reach conclusions and then act upon them, which I find really cool as well."



Kawaei, who plays Lisa, made the following comment about playing the role:
"I don't get many opportunities to do voice acting, so I was really nervous, and since my character is a high schooler she talks in a very energetic and cheery manner that's not the way I normally talk, I felt it was difficult to portray the character with just my voice alone, not using any kind of body language."
She was then asked to compare the character with her own high school life, and replied "I was a really plain and boring high schooler that never took a strong interest in any particular hobby or field, so I thought Lisa was wonderful."



When asked to comment on her role, Nozawa, who plays Hisui,
commented "(Since her name is Hisui) I thought she was a beautiful girl, and then she turned out to be a grandma...", making the room erupt in laughter.
She continued: "At first I thought she might be a scary person, but then it turned out to not be the case at all. When you you watch the movie, I think you'll all realize what a sweet grandma she is. The "lessons" this tale teaches are very easy to understand, so I definitely want all three generations to watch it."
She was then asked to comment on Ashida's, Kawaei's and Nakagawa's performances, and replied "I'm the type of person that watch the others pretty closely when they act", once again causing a burst of laughter. She then gave them her stamp of approval, saying "To be completely honest, it was very good! You could tell they were putting so much heart into it from the way their facial expressions were mimicking those of their character's... it was wonderful!"
Nakagawa was visibly delighted at receiving such a comment from a living legend of the voice acting industry like Nozawa, saying "Even though she's such a veteran, she's still extremely aggressive about getting work, and people all over the world are waiting for her voice... There's no other Japanese like her! She's the coolest veteran ever!"



And Nakagawa herself, who plays Riku, was asked for her thoughts on this year's "Pocket Monsters the Movie: Everyone's Story", which marks her 12th continuous appearance as a guest voice actor. "Everyone's Story truly is "everyone's" story", she replied, speaking with great passion. "I believe that no matter what age or sex you are, if you go watch this movie together with someone that means a lot to you, your bond will become even more special. Last year I went to see the movie 5 times, so this year I want to go see it twice that. And the art truly is wonderful! Satoshi is really animated this year, his bangs are really smooth, and the Rocket Gang look even hotter. The way the Pokémon move their mouths is also really subdued, and since the director is part of the first generation of Pokémon fans just like I am, I feel he's created a wonderful movie filled with love. Please make sure to witness this legend. I think that experiencing it live in the theater will cause it to remain in my heart forever. I want to discuss it to death on social media! And the Pokémon I'm 100% behind this time is Lucky" she said at great speed, all within the one minute time limit she had been given.



And since it's nearly summer, they were all asked what they'd do if they went on a summer date with a Pokémon.
Ashida was the first to answer: "Since it's summer, I thought going to the pool would be a good idea, but since Zeraora is an Electric type, that won't do", she said with a smile. "But I'm a real scaredy-cat, so I'd like it if we went to a haunted house together and Zeraora lit up the house to make it less scary".
Kawaei was next: "Since Eievui is really popular, I'd want to walk around Shibuya while hugging it, showing off to everyone", she said.
Nozawa then answered "I love food, so I'd like to go out for some barbecue (with Waninoko) and discuss today's movie with it".
Finally, a slightly uneasy Nakagawa said "If you mean the Pokémon would be my boyfriend, it'd be the cool Mewtwo-sama. Everyone loves Mewtwo-sama, and I want it to be like I'd have gone out with him, but then he wouldn't reply to my texts even though he had read them and was being active on social media, and I'd be like "Why?!"", causing the room to explode with laughter. "And then I'd be eating ramen all by myself when he'd suddenly show up in my room, and we'd have a movie date at home. And we'd watch Mewtwo Strikes Back and I'd ask him what he thought of it and he'd tell me to shut up and punch me! That's what I want!", she continued without even stopping to catch her breath, her passionate love for Pokémon bringing the room into a state of excitement.

The multi-person dubbing session came to an end with the cheery laughter that resulted. We'd like to thank all the actors for telling us so much about their passionate thoughts of this movie.

The movie's premiere is right around the corner! Please look forward to it, everyone!
